Description
Technical field
The present invention relates to a kind of deep-sea High-voltage-resistatransformer hydraulic cylinder sealing structure, specifically by utilizing dynamic sealing, isolation oil
Liquid, floating piston composition, belongs to hydraulic cylinder sealing technical field.
Background technology
Existing hydraulic cylinder mainly includes cylinder barrel, rear end cap, piston, piston rod and seal, and this kind of hydraulic cylinder typically should
Used in air pressure environment or short time in the pressure environment of change, requirement is substantially met.But for abyssal environment 0~
2000m, and briny environment is immersed in for a long time, it is unreasonable due to seal so that the poor sealing performance of oil cylinder.For above-mentioned
Problem, devise this deep-sea High-voltage-resistatransformer hydraulic cylinder sealing structure.
The content of the invention
For above-mentioned deficiency, the invention provides a kind of deep-sea High-voltage-resistatransformer hydraulic cylinder sealing structure.
The present invention is achieved by the following technical solutions：A kind of deep-sea High-voltage-resistatransformer hydraulic cylinder sealing structure, including it is dynamic
Sealing, isolation fluid, floating piston, end cap, cylinder barrel, piston rod, pouring orifice, it is characterised in that：Described cylinder inner fluid with every
Deposited in from fluid inside cylinder barrel, isolation fluid is high-voltage oil liquid, sets three dynamic sealings inside cylinder barrel, floating piston is arranged on
Outside to block its disengaging cylinder barrel by end cap inside cylinder barrel, end cap is connected with cylinder barrel, and 10mm is left between end cap and piston rod
Space, with extraneous seawater UNICOM, floating piston surface sets three seals interface, and floating piston sheet is as second dynamic sealing
Part, pouring orifice are arranged in floating piston motion section position.
The usefulness of the invention is：To 0~2000m of abyssal environment, and work long hours in briny environment, it is good full
The foot sealing property of hydraulic cylinder.On the outside of floating piston and contact with sea water, inner side is filled with pressure oil, and oil pressure is more than seawater pressure
Power, ensure that with extraneous sea water pressure balance, prevent seawater from penetrating into, and oil is separated with high-voltage oil liquid (pressure is higher than cylinder inner fluid)
Cylinder interior and seawater, and it is simple in construction, it is convenient to change.

Embodiment
The present invention is achieved by the following technical solutions：A kind of deep-sea High-voltage-resistatransformer hydraulic cylinder sealing structure, including it is dynamic
Sealing 2, isolation fluid 3, floating piston 4, end cap 6, cylinder barrel 7, piston rod 8, pouring orifice 9, it is characterised in that：It is oily in described cylinder
Liquid 1 is deposited in inside cylinder barrel 7 with isolating fluid 3, and isolation fluid 3 is high-voltage oil liquid, and the inside of cylinder barrel 7 sets three dynamic sealings 2, floated
Piston 4 is arranged on inside cylinder barrel 7, outside to block its disengaging cylinder barrel 7 by end cap 6, and end cap 6 is connected with cylinder barrel 7, end cap 6
10mm spaces are left between piston rod 8, with the extraneous UNICOM of seawater 5, the surface of floating piston 4 sets three seals, and floats and live
Plug 4 is used as second dynamic sealing device, and pouring orifice 9 is arranged in floating piston 4 and moves section position.
Operation principle：When hydraulic cylinder works are in the high pressure sea water environment of change, the pressure of extraneous seawater 5 directly acts on
In on 4 one faces of floating piston, at the same time, already by pouring orifice 9 will isolate fluid 3 (high-voltage oil liquid) inject hydraulic cylinder with
Between piston, acted on by isolation fluid 3 (high-voltage oil liquid) on another face of floating piston 4, and then promote floating piston 4 in work
Moved left and right on stopper rod 8, realize that fluid is isolated with seawater, and pressure balance.Assuming that extraneous seawater 5 enters the isolation (high pressure of fluid 3
Fluid), then three dynamic sealings 2 are additionally provided with inside cylinder barrel 7, are isolated with the cylinder inner fluid 1 of hydraulic cylinder.
For the ordinary skill in the art, according to the teachings of the present invention, do not depart from the principle of the present invention with
In the case of spirit, the changes, modifications, replacement and the modification that are carried out to embodiment still fall within protection scope of the present invention it
It is interior.
